About This Bearing Unit

This product is a flange bearing unit, also known as a pillow block unit, which integrates a bearing insert into a housing. The UCF designation is a common nomenclature for these units: “UC” refers to the insert bearing, which is a deep groove ball bearing with a spherical outer ring that allows for some initial shaft misalignment. The “F” indicates the housing type, which is a square, four-bolt flange. The unit is secured to a shaft using two set screws in the extended inner ring, providing a simple yet effective locking mechanism. This design makes the UCF204 a practical and reliable solution for many general-purpose industrial applications.
